A bolt catch lever for a firearm, including receivers and associated elements for receiving the bolt catch lever. In particular, a bolt catch lever comprising an upper lever arm, a lower lever arm, and a center element including a catch which is designed so as to be pivotable about a pivot axis in a lower receiver, where the center element has a recess for optionally receiving a connection section of a second bolt catch lever.

Ambidextrous bolts that allow a user to quickly and easily change the side of the firearm from which a spent casing is ejected by application of a simple switching mechanism that does not require disassembly of the firearm. Aspects of the disclosure also include debris shields for improving the longevity and reliability of extractors, firearms that are configured for ambidextrous operation, methods of using firearms, and methods of modifying firearms to incorporate ambidextrous functionality.

A safety selector comprises a first hub portion, a second hub portion, and a cam portion connecting the first hub portion with the second hub portion. The first hub portion is generally cylindrical in shape, having opposing faces and an longitudinal surface extending therebetween. Further, the first hub portion is segmented in it opposing faces, creating a first plane in the longitudinal surface. The first hub portion further comprises a pair of spaced apart detent sockets in the longitudinal surface face, a connecting groove extending between the detent sockets, and a detent notch in an outer one of the circular faces exposing one of the detent sockets. The cam portion comprises a recessed face and a cam face. The first plane is substantially parallel with the recessed face.
